Hi Burgermeister,
I am looking in to it now.
With the chinese device I have I was able to code my blank key, but I never thought of going to another car.
The device I have reads the info from the CAS and then writes it to the key.
So I connect via the OBDII port.
The key has to be a blank key, meaning that the IC hasn't been programmed.
Once the IC is coded, it burns fuses off so it cant be reprogrammed again, hence why you need to replace the IC inside the key to re-code it again.
You cannot re-code an already coded key.
I never thought of doing this, it was just a way to make my own key.
Shows how different the criminal mind thinks to a normal persons mind.
hmmmmmm
So, I guess, yes, it is do-able.

Hi Ace... where did you get the blank key from? I'm trying to retrofit comfort access to my E90, but the first obstacle is that I cannot get a blank key from the stealership. Also tried getting a VIN specific key from the stealer, but rejected.

Once again, thanks for your great work! I have most parts now, except the door handles and the key fob.

One quick q: does the non CA key still work after the retrofit? If the CA retrofit fails for some reason, I suppose the CA key would still work by inserting it and using it as if it were non CA?

Hi Zuma,
just get the CA Key Fob and the IC's off eBay, mail them to me, I will fit the blank ones and then I will mail it back to you done.
No fee, just pay the postage...it's a two minute job.
Regards
Ace

Hypocrite the guy get's banned and comes here again under another nickname calling people on this Forum and the mod's NAZI'S .
So what's up with that that's crossing the line,but then again it's my opinion good luck

Well... I need his help to work out the retrofit for a E90... He's been very helpful so far, until his account AceFX got banned... I'm not aware of other posts where the discussions might have gotten a bit heated...
